Objective of Upgrading
Main objectives of WWTP Upgrading :  To improve treatment performance of existing system in order to comply with standard requirement (Non compliance to requirement. Standard)  To amplify treatment capacity of system to cater for additional load.  To identify plants which can be y p decommissioned and transfer flows to the upgraded plant. (Rationalization – Economic efficiency)

Consideration for Upgrading Works
Land Area Availability/ Land Status Catchment Strategy Existing Process Existing Structure Existing Capacity Plant located Above Water Intake Financial
•to consider orientation of new structure to fit in reserve area •can only be done if land is surrendered to Government •parallel with long term Catchment Strategy •design PE to future growth •upgrade to same system (EA, AL, SBR) •upgrade to mechanized system (BS, BF, IT) •<10% PE* increase, no structure change •Sufficient free board required

•calculate existing capacity to determine actual capacity

•upgrade to fully mechanized plant •higher treatment imposed •joint scheme to have own funding •SCC discounted based on offset from construction cost

Types of Upgrading Works
• Minor upgrading, e.g. small change of pumps or retention time, time raise of water level level, setting of blower/blower capacity or extra area of sludge drying beds and no structural change • The capacity of upgrading works – usually <10% of existing capacity
Minor Upgrading

• Major upgrading includes changing system type to capture the extra flow from new development • Involves whole STP, e.g. changing of pumps, blowers, new additional structure, scrapers, etc. • The capacity of upgrading works – usually >10% of existing capacity

 70 STPs were upgraded with a total cost of RM140 million. Additional cost of RM2 Billi Billion was allocated t upgrade 13 major STP under th t f ll t d to d j STPs d the JBIC Loan.  To date about 100 Nos. of non performance STPs were upgraded to a better system
